0322537 EVINRUDE LATCH HANDLE AND SHAFT ASSEMBLY,Front

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
The Engine Control Module (ECM) contains no moving parts. Replacement of the ECM can be costly. Replacement can also be a time consuming task. Follow the troubleshooting procedures in this manual in order to ensure that replacing the ECM will correct the problem. Verify that the suspect ECM is the cause of the problem.Note: Ensure that the ECM is receiving power and that the ECM is properly wired to the negative battery circuit before a replacement of the ECM is attempted. Refer to Troubleshooting, "Electrical Power Supply Circuit - Test".A test ECM can be used to determine if the ECM is faulty. Refer to Troubleshooting, "Test ECM Mode".
If the flash file and engine application are not matched, engine damage may result.
Perform the following procedure in order to replace the ECM:
Record the configuration data:
Connect Cat ET to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
Print the parameters from the "Configuration" screen on Cat ET. If a printer is unavailable, record all of the parameters.
Obtain the customer passwords from the vehicle owner. Access the customer specified parameters with Cat ET. Use the Troubleshooting, "Customer Specified Parameters Worksheet" to record the customer parameters.Note: If the customer passwords are not available proceed to Troubleshooting, "Customer Passwords" for details that are related to customer passwords.
Record ECM lifetime totals. Use the Troubleshooting, "Customer Specified Parameters Worksheet (Current Totals Worksheet)" to record the ECM lifetime totals.
Record the mileage from the vehicle odometer.
Record any logged diagnostic codes.
Use the "Copy Configuration/ECM Replacement" feature that is found under the "Service" menu on Cat ET. Select "Load from ECM" in order to copy the configuration data from the suspect ECM.Note: If the "Copy Configuration" process fails and the parameters were not obtained in Step 1.b, the parameters must be obtained elsewhere. Some of the system configuration parameters are stamped on the engine information plate. Most of the parameters must be obtained from the factory. Parameters that are related to customer specified parameters must be obtained from the customer or from the Original Equipment Manufacturer (OEM).
Remove the ECM:
Turn the keyswitch to the OFF position.
Disconnect the P1 and P2 connectors from the ECM.
Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
Remove the fuel lines (if equipped) from the ECM.
Disconnect the ECM ground strap.
Remove the mounting bolts from the ECM.
Install the replacement ECM:
Use the old mounting hardware to install the replacement ECM.
Connect the fuel lines (if equipped).Note: Verify that the fuel lines are installed correctly. The fuel lines must not put tension on the ECM . Rubber grommets are used to protect the ECM from excessive vibration. The ECM should move slightly in the rubber grommets. If the ECM cannot be moved slightly, check that the fuel lines are not pulling the ECM against one side of the grommets.
Connect the ECM ground strap.
Connect the P1 and P2 connectors. Tighten the ECM connector (allen head screw) to the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque value.
Configure the replacement ECM:
Flash program the latest available flash file into the ECM. Refer to Troubleshooting, "Flash Programming" for the correct procedure.
Use Cat ET to match the engine application and the interlock code if the replacement ECM was used for a different application.
If the "Copy Configuration" process from Step 1.b was successful, return to the "Copy Configuration/ECM Replacement" screen on Cat ET and select "Program ECM". Proceed to Step 4.e when programming is complete.
If the "Copy Configuration" process from Step 1.b was unsuccessful, manually program the ECM parameters. The parameters must match the parameters from Step 1.b.
Program the engine monitoring system, if necessary.
Calibrate the engine speed/timing if there is a diagnostic code for speed/timing sensor calibration. Refer to Troubleshooting, "Engine Speed/Timing Sensor - Calibrate".
